An accelerator which was designed to plug into the CPU Fast Slot of the
A3000 and A4000 series machines. The Cyberstorm PPC is an amazing piece
of kit providing both a 68k processor and a PowerPC processor. The idea
is that the PowerPC can be used to run software which supports it, much
faster than any 68k processor can, with the 68k providing compatibility
with existing 68k Amiga software. There is a surprisingly large amount
of PowerPC software for the Amiga, and even alternative PowerPC
operating systems such as Linux can run on this card. The card also
includes a SCSI-3 Ultrawide (68pin) controller and an expansion port
for the Cybervision PPC graphics card. This card was originally
manufactured by Phase 5, but after they went into liquidation DCE
bought the rights and manufactured at least a limited number of units.
A working prototype of this card is also available, although it was
only ever released to developers.

During the reset sequence it
is possible to hold down the ESC key and enter a configuration menu for
the card. From this menu you can configure various things about the
card such as which ID the scsi controller uses, inititial system setup
such as the supervisor mode of the 060 and other things like RAM
timings. The ROM for the card can also be flash-updated. By holding
down M you can disable the memory on the card, holding down S disables
the on-board SCSI controller and holding down A disables both the
memory and the SCSI controller.

Fitting in an A3000

Fitting this card to an A3000 may require an INT-2 modification (but
this has not been confirmed). All Phase 5 versions of this card were
manufactured with low profile SIMM slots which mean the card physically
fits in an A3000 without any problems. However the initial boards
manufactured by DCE used vertical standing SIMM slots which means if
your board is one of these, you may have problems physically fitting it
inside an A3000 due to height restrictions.
